GASOLINE-RESERVE CONTROL.

Application filed January My invention relates to devices for automatically cutting ofi the flow of liquid from containers before the entire supply is exhausted, and while said devices may be employed in connection with various kinds of containers, in the present instance I have shown one installed in a container for holding a supply of gasoline for the internal combustion engine employed in the propulsion of a motor vehicle of the Ford type.

With one of the devices installed in a gasoline tank as shown, the inconvenience arising from running out of gasoline while traveling on the road may be avoided, as the supply to the engine is automatically cut off after receding toa predetermined level, causing the engine to stop and thus notify the driver that the tank should be replenished before the limited reserve of gasoline therein is exhausted.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a vertical cross section of a gasoline tank equipped with the device which is shown with. the cut-oil valve in open posi tion.

Fig. 2 is a fragmentary section similar to Fig. 1, excepting that the cut-off valve is in closed position. r

Fig. 3 is a view similar to Fig. 2, excepting that the cut-off valve is latched in open position, so that the reserve gasoline within the tank may flow therefrom.

Fig. 1 is an irregular longitudinal section on line IV IV of Fig. 2.

Fig. 5 is a detail of the cut-E valve and associated parts.

Fig. 6 is an enlarged cross section on line VI-VI of Fig. 3.

Referring now in detail to the different parts, A designates a gasoline tank and B the usual stop cock embodying a sediment chamber C and from which the feed-pipe D leads to the carburetor of the engine, not shown.

Referring now more particularly to the parts constituting my invention, 2 designates a nipple, the upper end of which is threaded through the bottom of the tank A in lieu of the upper threaded and E of the stop cock B, which, in the present instance, is threaded into the lower end of the nipple 2, as shown by Figs. 1 to 1, inclusive.

The upper end of the nipple 2 is provided with a beveled valve seat 4; surround- 13, 1925. Serial No. 2,171.

ing an outlet port and adapted to receive a correspondingly shaped valve 6, having an upwardly extending stem 8 carrying a float 10 of cork or other suitable material fixed to said stem 8.

The upper'portion of the stem 8 has a slidable connection with a sleeve 12 in which it is retained by an integral head 14-. The sleeve 12 is reciprocably mounted in a tubular guide 16-having a pair of diametricallyopposed arms 18 'fixed at their lower ends to the nipple 2. In addition to constituting a support for the guide 16, the arms 18 form a guide for the float 10, which has diametrieally-opposed grooves 20 through which said arms 18 extend.

The sleeve 12 is connected at its upper slotted end by a pivot 22 to a latch 24 provided at its lower portion with oppositelydisposed notches 26 and at its upper portions with a suitable float 28.

3O designates a rod terminating at its upper end in a handle 32 and connected at its lower end to a hook 34 extending through a longitudinal slot 36 in the guide 16 and ixed to the sleeve 12. The rod consists of two sections 38 and 40 having a slip joint connection L2 in order that the sleeve 12 and parts attached thereto may move down warely independently of the handle 32 to a limited extent while the same rests upon the top of the tank A.

The operation briefly stated is as follows: As the tank A is supplied with gasoline the same carries the float 1O upwardly until checked by the lower end of the guide 16, as shown by Fig. 1. As the float 10 is carried upwardly it unseats the valve 6, so that, as-' suming that the stop cock B is open, gasoline within the tank A recedes with use to a predetermined point, and the float 1O descends with the valve 6 until the same engages the seat 4, Fig. 2, thereby automatically cutting off further flow of gasoline to the feed pipe D. Cutting off the gasoline from the feed pipe D, causes the motor, not shown, to stop, thereby notifying the driver that there is only a limited supply of gasoline within the tank A, which should be replenished at the first filling station, or other source of supply. In order to be able to proceed to a filling station, or other source of supply, on the limited reserve of gasoline within the tank A, the driver pulls the handle 32 upwardly and, through the interinediacy of the sleeve 12, raises the floats 10 and 28 until checked by the float 10 contacting the lower end of the gu de 16, As the sleeve 12 moves upwardly its upper end rises above the guide 16, permitting the latch and the float 28 to swing downwardly to the position disclosed by Fig. 3 and thereby securing the float 10 and the valve 6 in open. position so that the reserve gasoline may flow to the feed pipe D and thus permit the motor vehicle to proceed. The parts remain in the position disclosed by Fig. until the tank A is replenished with gasoline, the rising level of which rttains the floatlt) in .aised position and lifts the float 8 until the latch lei is released from the guide 16. i

the comb ned weight of the float 28, the latch 24, the sleeve 12, the hook 34, and the rod section 00 then vforces said sleeve 12 downwardly until checked by the hook 234: reaching the lower end of the slot 36. As the sleeve 12 moves downwardly it carries the latch 24. into the upper portion oi the guide 16 leaving the float 10 and the valve (3 tree to move downwardly and close the nipple 2 when the level of the gasoline again falls to the predetorn'iined point.

From the foregoing description taken in connection with the drawing, it is apparent that the device isautomatic in operation, e);- cepting when it becomes necessary to man-- ually open the. valve 6 to permit the latch 24. to assume the active position disclosed by 3, sot-hat the reserve gasoline may flow to the ieedpipe D. It is also apparent that I have provided comparatively inexpensive and simole device which is well adapted for the. purpose intended; and while I have shown and described the preferred form of said device I reserve the rigl'it to make such chances in the construction, combination and arra. ement of parts as properly fall within the spirit and scope of the invention as claimed.

Having thus described my ivention, what I claim and desire to secure by Letters Patent, is:

l. A device of the character described con sisting of a i'ioat-actuated valve, latch-means for securing said valve in open position, and float-means independently movable of said valve for releasing said latch-means from active position so that the valve may close.

2. A device of the character described consisting of a float-actuated valve, a guide for said valve, a member movable in said guide and having a loose connection with said valve, a latch attached to said member and adapted to engage said guide and hold the valve open, manual means loosely connected to said member to move the same to a position allowing said latch to hold the valve open, and means for releasing the latch so that the valve may close.

33. A device. of the character described conot a float-actuated valve, a guide for said valve, a sleeve movable in said guide and having a loose connection with said valve, a sleeve and adapted to engage said guide and hold the valve open, a handle loosely con-v "ed to the sleeve to move the same to a poon allowing said latch to hold the valve open, and means for releasing the latch so the valve may close.

-Ll-. A, container having an outlet at its lower portion with a valve seat, a float-actuated valve for clos g said outlet, aguide in the container for said valve and lined to the valve seat, a member in the container movable in said guide and attached to the valve to raise the same from its seat, manual means extending through the top of the contain ,r and loosely connected at its lower end to said member to raise the same, latch means i nd within the container to engage over urde and hold, said member in raised position, and meansindependent of the valve for automatically releasing said latch means. 5. liquid holdingcontainer having an out et, a float actuated valve for closing-said outlet. a rod 4; r ising said valve extending through the top or" the container and consisting of two loosely-cormected sections to enable the upper section to descend until its upper end rests on top of the container after the valve has been raised, latch means within the container for holding the valve in raised position, and means within theconta ner for releasing said latch means when a predetermined amount oi liquid; is placed in the tank.

in testimony whereof I afiix my signature.
